  1. Cobra ESD 7570 – The Best Affordable Radar Detector

This device – Cobra ESD 7570 – will not make you dig your hands so deep into your pockets, but it comes with some serious punch. It is a sleek-looking product and it is also compact it can be mounted to your windscreen with the use of suction cups, and it also comes with a display that you can easily see, giving you data even under the glaring sun.

This model’s display has several sections that come in certain colors for the various bands that the people of the law enforcement make use of so that you can immediately be notified of what it is you are up against.

There is a feature that comes in handy, and this is the city or highway feature. When you are in a densely populated area, there are certain other things that could set off your radar detector like store alarms and various other signals. When you set your radar detector to city mode, it would help to reduce these fake alarms. When you are on the expressway, and this happens when you are out in non-urban areas, signals almost invariably come from law enforcement; a plant certainly will not make your detector go off. When you are on the highway mode, this is taken into account.

This model’s 360-degree revolution that is called the LaserEye helps to detect signals, it does not matter where they are from. The ESD 7570 will alert you if the alert is coming from behind your vehicle. This device comes with safety notifications when there is a detection of an emergency vehicle, like an ambulance, or when it detects that you are getting closer to a railroad crossing, and other hazards.


  1. Valentine One V1 – The Best Mid-Range Radar Detector

This model’s design and display have a 90s look and that is because they actually are, but the device is one of the best radar detector models available on the market. It comes with two rear antennas, an impressive scope, and laser detection, this model helps give you a clean driving record.

One beautiful thing about this design is its ability to notify you of radar signals when you are close to them. While many radar detector models on the market only notify you of any signal that is within your vicinity, Valentine One’s model tells you of the precise direction of the radar signal. With the antennae that you can find in front and at the back of the car, you will be able see just where the speed signal is reading from and the type of band that is being used.


If the arrow on the top of the device activates and the Ka category lights up, a police speed trap lies ahead of you. You will know you have passed it once the arrow pointing down lights up. The Valentine One makers have a patent on their arrow indicators till the year 2011, the Escort Max 360 comes with a similar feature.

As with any device, there are always advantages and disadvantages, and this model is no different, as it has its own downsides. While this drawback is not totally ruling out this product, it has the ability to do more than expected when you expect it to do something as basic as picking up radars, even when it comes to radars that are given off by detectors that are not from law enforcement devices, it can easily pick it up, giving you a wrong signal. But such a drawback on such a great model should not make you look away from choosing this device as your detector.

The fact is, many people would instead want to own a radar that overcompensates at what it does than a device that fails to not notify the driver even at places when it is supposed to.

The X and K band radar detectors can also be turned off by this device, though, you should be careful, seeing as some law enforcement agents still make use of the bands that are not K-bands. This device’s dependability and reliability when it comes to its notifications and its display system makes it one of the top brands on the.

What is a battery powered or a cordless radar detector?

The battery powered radar detectors come with all the mod-cons of a regular plug-in device, but they do not come with those distracting, annoying cables. All what you need to do is to attach it to your car’s dashboard or its windshield, switch it on and you begin your drive.

These devices are a great accompaniment for the drivers who use multiple cars, since they are very small, easy to transport, and they are also simple to configure. Some models available on the market have a very long battery life, and what this means is that you get more driving time, and you would be required to spend less time pulling over to recharge or to switch batteries.

Different Wavelengths and Bands


So that you can get the best results, your radar detector must be sensitive to three main radar frequencies. The X-band radar is the lowest in terms if frequency, but it is high in output, with the radar waves that fall between 7.0 and 11 Gigahertz.

What this means is that it is easy for you to detect at longer distances. Although, the X-band is the oldest type of wavelength that is used in police speed guns and it isn’t widely used again.

Any device that is other than the police radars can produce or emit X-band signals; and most of these devices could be garage door openers, weathering monitoring equipment, blind spot monitoring systems, microwave towers, and many other modern radar technology.


This was adopted by the police service just a few decades ago, K-band is a higher power alternative to the original standard, which is the X-band. The K-band has quite a shorter wavelength, with a frequency of 18 – 27 Gigahertz, and it is in the microwave range of frequencies.

Because of the K-band’s shorter wavelength, the original K-band was been sectioned into three other wavelengths, Ka-band, K-band, and Ku-band.


The Ka-band; this one which was introduced in the year 1983, is what is called the new kid on the block. It has frequencies that are found in the microwave segment of the electromagnetic spectrum. The ka-band is a bit more complex than its contemporaries – the X and K, and it also exists within the frequencies of 26.5 – 40 Gigahertz, so wavelengths over one centimeter to just 7.5 millimeters.

The much older police radar guns that operate on either X or K-bands do so only at the frequencies of 1 or 2. Ka runs on as many as five frequencies. When getting a radar detector, it is prudent that you get the one that can detect as many wavelengths, and that has laser detection.
